APPARATUS FOR MAKING ICE.

To all 2072 am it may concern Be it known that I, WASHINGTON EVERETTPARSONS, a citizen of the United States, and resident of the city,county, and State of New York, have invented certain new and usefulImprovements in Apparatus for Making Ice, of which the following is aspecification.

This invention relates to ice making apparatus and more particularly tosystems in which the ice is made in cans provided with interiorlyarranged brine circulating means.

The invention has particular reference to the means for connecting themain brine supply conduit with the interiorly arranged circulatingmeans.

The objects of the invention are to provide the usual freezing tank witha brine supply main arranged in or adjacent to the upper part thereof,where it is readily accessible, and to provide the cans with suitablesupply pipes for the interior, circulating means, said pipe beingarranged on the exterior of the cans and connected with outlets in thesaid main by readily detachable means held in cooperative relation bythe buoyant effect of the brine in the tank on the can.

It has been heretofore customary to provide the cans with a heavy bottomfor the purpose of weighting them to overcome the buoyancy of the brineand it is one of the objects of my invention to have a lighter can andto utilize the buoyancy of the brine to hold the pipe which conveys thebrine to the interiorly arranged circulating means, in cooperation withthe outlet from the main supply conduit. The pipe for conveying thebrine from the supply conduit to the interiorly arranged circulatingmeans is located on one side of the can and therefore the buoyant eifectof the brine on the can tends to tilt the latter and, in order toobviate this tilting action, I have provided means above each can forholding the latter in proper position.

A further object of the invention is to provide a readily detachableconnection between the said pipe at the side of the can and the mainsupply conduit so that the can may be readily placed in or removed fromthe tank.

Other objects and the features of novelty will be apparent from thefollowing description taken in connection with the accompanying drawingsin which,

Figure l is a longitudinal section through Specification of LettersPatent. Application filed December 20, 1912.

Patented Nov. 17, 1914. Serial No. 737,907.

a water can and showing its relation to the ad oining cans in the usualfreezing tank; Fig. 2 is a section on the line 22 of Fig. 1; Fig. 3 isan enlarged section on the line 38 of Fig. 2; Fig. 4 is an enlargedsection of the pipes at the bottom of the can for conveying the brine tothe interiorly arranged circulating pipes; Fig. 5 is a section on theline 55 of Fig. 3.

Referring to the drawings, indicates a portion of a freezing tank havinga bottom 11, and having at its top the usual cross beams 12, 13 and 14which form spaces through which the water cans 15 are passed in beingplaced in or removed from the tank and support the covers for thesespaces. The tank is usually filled with brine to a level slightly belowthe tops of the cans 15 and the brine is cooled by being circulated fromthe tank through a suitable coolingapparatus and then returned to thetank, or the tank may have arranged therein, between the rows of cans,the circulating pipes 16 for the brine cooling medium.

I provide 011 the interior of the cans the upwardly extending pipes 17which are closed at their upper ends and have their lower ends open tothe interior of the tank, as clearly shown in Fig. 1. \Vithin the pipes17 are the smaller pipes 18 which are connected below the bottom of thecan with a suitable supply conduit. This conduit is preferably formedwith the reducing Ts 19 by means of which the size of the conduit isreduced beyond each T so as to provide a more positive circulation ofthe brine through each of the pipes 18. Referring to Fig. 4, it will beseen that the conduit is provided with an L 20 at one side of the canand this L is connected with the first of the Ts 19 by means of a pipesection 21. Beyond the first T 19 is a pipe 22 which is smaller than thepipe 21 so as to restrict the flow of brine and cause the same to risein the pipe 18. From Fig. 1 it will be observed that the pipe 23 whichis beyond the second T 19 is smaller than the pipe 22. The L 20 has oneof its openings directed upwardly at the side of the can and connectedwith a pipe 24 which has at its upper end a special fitting 25 securedto the side of the can.

Arranged below the beam 14? is one of the main brine supply conduits 26,which is provided in its bottom adjacent the fittings 25 with specialoutlet fittings 25 which areshown in detail in Figs. 3 and 5. Thesefittings are secured to the lower side of the conduit 26 and have abaffle or deflector 27 extending upwardly into the conduit 26 with theopen side 28 thereof directed in opposition to the flow of brine throughthe conduit so that the brine will be deflected through the fittings 25.Below the conduit the fittings 25 are provided with two branches 29 and30 adapted to be connected with the fittings 25 on adjoining cans sothat the interiorly arranged pipes in two cans will be supplied from oneoutlet in the conduit 26. The passages 29 and 30 are preferably oval inform, as shown in Figs. 3 and 5 and the fittings 25 are each providedwith a recess 31 in the upper side thereof in which is arranged asuitable gasket 82. Each fitting 25 is provided with a central passage33 which communicates with the passage 29 or 30 and the lower edges ofthe walls of the passages 29 and 30 engage the gaskets 32 and have acertain amount of lateral movement thereon so that a tight joint may beprovided between said'lower edges and the gaskets without having theparts in exact alinement.

The buoyancy of the brine in the tank on water cans of the usual sizecauses the cans to be forced upwardly so that the fittings 25 on thecans will be pressed against the lit tings 25 on the conduit 26. Theengagement of these parts prevents the upward movement of that side ofthe can and therefore the can has a tendency to be tilted. In order tohold the can down to its proper position, I arrange on the underside ofthe cover 34. for the space above each can,.a cleat 35 which is adaptedto engage the upper edge of the can on the side opposite the fitting 25,as shown in Fig. 1, so that the can will be subjected to the weight ofthe cover.

It is believed that the foregoing description taken in connection withFig. 1 will make it perfectly clear how the can is held, in the positionshown, against the buoyant force of the brine in the tank. When it isdesired to remove a can from the tank, as when the water in the can hasbeen frozen, the cover 3a is removed and the can pressed downwardly topermit disengagement of the fitting 25 from the fitting 25 on theconduit 26. This disengagement is effected by moving the can laterallyto the left in Fig. 1. Vhen the parts are disengaged the can may bereadily lifted out of the tank and replaced by-another can by a reverseof this operation. When the can is being lifted out of the tank thesuction in the pipe 17 will draw practically all of the brine out of thepipes 18 and the pipes connecting them with the fitting 25.

In order to protect the pipes at the bottom of the cans the latter areprovided with suitable leg-s 36, by means of which the cans may besupported when out of the tank without the pipes being subjected to theWeight thereof.

By having the conduits 26 arranged at the top of the tank 10 instead ofat the bottom of the tank, as has been the custom in prior systemsemploying the internally arranged circulating pipes in the water cans,the conduits are readily accessible for repairs and other purposes andit is possible to use a much lighter can and at the same time have athoroughly efficient connection between the conduit and the interiorlyarranged circulat-- ing pipes.

It will be obvious to those art that various changes may the details ofconstruction and arrangement of the parts of my invention, within thescope of the appended claims, and therefore I do not wish to be limitedto the exact details shown and described.
